B cut-out silks 33 are fixed between block 11.
In delivery pipe 2, the air outlet of inflation film manufacturing machine 1 is persistently dried, and plastic sheeting is presented cylindric, now transfer block 4
In plastic sheeting, microprocessor control A air pumps 6 start afterwards, the port pumping in transfer block 4, through transfer block 4
The port exhaust of upper end, now produces negative-pressure adsorption effect, plastic sheeting is attracted to by the effect of passage 5, transfer block 4
The surface of transfer block 4；After certain time（Ensure that plastic sheeting is adsorbed by transfer block 4）, microprocessor control A electric pushrods 3
Work, transfer block 4 is promoted to move down, so as to drive plastic sheeting to move down, when the output end of A electric pushrods 3 is elongated to most
When final position is put, now transfer block 4 is reached at back cover unit, and plastic sheeting bottom is stretched out from the lower end of positioning pipe 15.
Shrouding 17 at back cover unit is now in vertical direction, ensure that the unobstructed of positioning pipe 15, enables transfer block 4
Pass through.When the output end of A electric pushrods 3 is elongated to final position, microprocessor control B air pumps 23 start（Startup opportunity can
To be determined by setting time, start corresponding travel switch when also can be elongated to final position by A electric pushrods 3 and realize）,
It is evacuated at the port connected with branch pipe 24, so as to produce negative-pressure adsorption by the effect of ventilation duct 22 and air vent 18, shrouding 17
Effect, similarly, at the same time, the direction of the exhaust of microprocessor control A air pumps 6 is changed, and now A air pumps 6 are passed through in transfer block 4
The port pumping at end, the port exhaust in transfer block 4, now dry at passage 5, plastic sheeting is blown off transfer block 4, therefore
Plastic sheeting is attracted on shrouding 17.
After certain time（Ensure that plastic sheeting is adsorbed by shrouding 17）, the output end of microprocessor control A electric pushrods 3
Reverse operation, transfer block 4 is driven to move up, now magnetic valve 7 is closed, and inflation film manufacturing machine 1 does not continue to blow into delivery pipe 2.
Similarly, now microprocessor control mode motor 19 is started working, and is driven shrouding 17 to be gradually rotated up by rotating shaft 20, is made envelope
Plate 17 mutually closes up, and therefore plastic sheeting bottom is gathered, after certain time, gather completion, now microprocessor
Control heating wire 21 is worked, and plastic sheeting bottom is heat-sealed.
After the completion of heat-sealing, because the extruding of shrouding 17 has unnecessary fold part, therefore flash trimming cell operation, pass through rotation
The circumgyration incision effect of knife 30, unnecessary fold part is pruned.Torque motor 19 and C electric pushrods 27 and driving during this
Motor 29 is interaction relation；While torque motor 19 drives shrouding 17 gradually to gather, C electric pushrods 27 promote support block 28
Gradual upward sliding, motor 29 drive rotating knife 30 to start to rotate in sleeve 26, when shrouding 17 gathers completion, C electricity
The impetus of dynamic push rod 27 causes rotating knife 30 to prune fold part just.
It is micro- when transfer block 4 is all introduced into delivery pipe 2 during A electric pushrods 3 drive transfer block 4 to move up
Processor control shearing device is started working（Work opportunity is by being previously set）, B electric pushrods 14 start, and promote sliding block 11 to exist
High-speed slide in chute 10, the effect of silk 13 is now cut off by A, you can plastic sheeting is cut off, realized to plastic sheeting
Segmentation.In the present embodiment, A cut-out silks 13 and B cut-out silks 33 are respectively at the left and right sides of connection strap 12, can make B electric pushrods
When 14 band movable sliders 11 move back and forth, plastic sheeting can be cut off.
After plastic sheeting cut-out, round bottom polybag is completed by production, now the exhaust of microprocessor control B air pumps 23
Direction conversion（Work opportunity is by being previously set）, now ventilating opening air blowing, round bottom polybag can be removed.Repeat above-mentioned
Process, you can constantly produce round bottom polybag.
